Why does the child keep blinking?

As a child grows, new problems may arise every day. For example, a child likes to blink constantly. This tiny action may seem to have no obvious effect on growth, but in the long run it must be caused by certain factors. Normal blinking movements maintain a certain frequency, so what is going on if a child keeps blinking and exceeds the normal frequency? Let’s understand the specific reasons together.

Common reasons why children blink frequently:

1. Inflammatory stimulation: This is the most common cause, which may be caused by infections such as bacteria, viruses, chlamydia, etc., such as conjunctivitis, keratitis, etc.

2. Congenital inverted eyelids and trichiasis: Some children have congenital inverted eyelids (medically known as eyelids), which causes the eyelashes to fall on the surface of the eyeball, irritating the cornea (the surface of the black eyeball) and causing tears.

3. ADHD in children: refers to the sudden, involuntary contraction and movement of a certain part of the child's body, such as blinking, frowning, twisting the mouth, shrugging, etc., inattention and hyperactive behavior changes.

4. Eye fatigue blinking: including visual fatigue, such as refractive errors, especially uncorrected hyperopia, myopia, and astigmatism, which cause visual fatigue of the eyes.

5. Neurogenic blinking: It is caused by the frequent contraction of the nerve fibers that control the orbicularis oculi muscle after being stimulated.

6. Habitual blinking: Some children have a history of frequent blinking due to one of the above causes. After treatment and the cause is eliminated, they still retain the habit of frequent blinking.

The above are several reasons why children keep blinking. When parents find that their children are blinking frequently, they need to conduct timely eye examinations and diagnose the cause of the blinking before providing symptomatic treatment. No matter what causes the blinking, adults should pay attention to the rational use of children's eye time and avoid letting children suffer from excessive eye fatigue.
